24AA025E48-I/SN Typical application Circuitry

24AA025E48-I SN

The 24AA025E48-I/SN is a specialized EEPROM (Electrically Erasable Programmable Read-Only Memory) from the 24AA series, notable for its embedded globally unique 48-bit MAC (Media Access Control) address. This feature makes it particularly useful in networked applications, where a unique identifier is required for Ethernet, Wi-Fi, and other network communications. The presence of a pre-programmed MAC address simplifies design processes and inventory management for devices requiring network connectivity. Additionally, it offers extra EEPROM storage for user data, making it versatile for storing configuration settings, device parameters, or small amounts of data that need to persist across power cycles.

1. Operating Voltage: The 24AA025E48-I/SN is designed to work within a 1.7V to 5.5V range, accommodating a wide variety of power supply levels. This flexibility ensures that the device can be easily incorporated into systems operating at standard logic levels, facilitating its use in both low-power and traditional 5V systems without the need for additional voltage regulation.

2. Pin Configuration and Connectivity: Enclosed in an 8-pin SOIC (SN) package, the device's pin assignments are as follows: 1. A0 (Address Input), 2. A1 (Address Input), 3. A2 (Address Input), 4. VSS (Ground), 5. SDA (Serial Data Line), 6. SCL (Serial Clock Line), 7. WP (Write Protect), and 8. VCC (Power Supply). Connections involve tying VCC to the power supply within the specified voltage range and connecting VSS to the system ground. The SDA and SCL pins facilitate I²C communication, requiring pull-up resistors for proper bus operation. A0, A1, and A2 are hardware address pins, allowing multiple devices on the same I²C bus by setting different addresses. The WP pin offers write protection for the EEPROM, preventing unintended modifications to the data.

3. Circuit Integration Guidelines: For circuit integration, ensure the VCC and VSS pins are correctly powered and grounded. Interface the SDA and SCL pins with the corresponding I²C bus lines on the microcontroller or processor, incorporating pull-up resistors (typically in the range of 1kΩ to 10kΩ) to maintain line states when not actively driven. Configure the A0, A1, and A2 pins according to the desired I²C address scheme, which is especially important when using multiple devices. The WP pin can be connected to VSS to enable writing or to VCC (possibly through a GPIO pin for selective control) to protect the EEPROM content.

4. Additional Features for Enhanced Operation: The embedded MAC address in the 24AA025E48-I/SN is read-only, ensuring its uniqueness and integrity. For applications utilizing the user-accessible EEPROM area, consider implementing error-checking mechanisms, such as checksums or CRCs, to verify data integrity after read operations, especially in environments prone to electrical noise.

5. Application Scenarios: The 24AA025E48-I/SN is ideal for networked devices requiring a unique hardware identifier, including but not limited to IoT devices, Ethernet controllers, wireless communication modules, and smart appliances. Its additional EEPROM space provides a convenient location for storing network configuration settings, device calibration data, or application-specific parameters, enhancing the device's utility in connected applications.

The 24AA025E48-I/SN embodies a practical solution for adding non-volatile storage and a unique network identifier to a wide range of electronic products. By streamlining the integration of network capabilities and providing additional memory for user data, this EEPROM enhances the functionality, reliability, and connectivity of modern electronic systems.
